Nexus One on 3G, not switching to HSDPA

Hi! I have been browsing the Nexus One forums for a while now, but I seem to have a strange problem.
I had a Nexus One that was working fine, but there was a piece of dust under my screen. It switched to HSDPA, and I had none of the issues that I have now. I sent it to HTC, but they didn't want to repair it, because it was rooted. I think they flashed something into the phone, because ever since the internet connection is very buggy. 3G (UMTS) didn't cause any problems then, but now if I hold my hand at the bottom of the nexus, connection indicator lowers (Cell Viewer: ranging from -1 to 8). When I hold the phone up int he air the connection varies between 14 and 24 (UMTS). The phone doesn't switch to HSDPA AT ALL!
I tried the hsxpa-tweak in build.prop, but it didn't help. I am using Cyans latest stable. I have wiped, installed stock, upgraded to cyan again, and tried staying on the stock rom, to no avail.
Is there something really stupid that I am not seeing? Or would it mean that the transporter has damaged my phone antenna by dropping it? :O

What makes you believe you're not getting HSDPA? Have you tested the actual speed of your connection? Keep in mind, on an unrooted Nexus One, your signal indicator will always show 3G even when HSDPA is active. It only shows the H when you're using a custom ROM.
Also, the signal fluctuation when covering the bottom of the phone is well documented at this point. It's normal.

HSDPA is only active when the network deems you need it, it'll just sits on 3G all other times.

Funny..I'm on HSPA all the time when on 3G..never saw UMTS not one. Yet on a cliq I saw UMTS...

I used Cell Viewer to test signal type. I was consistantly on HSDPA before it got sent in to HTC.

Assuming you're in the U.S. and on T-Mobile, the following thread covers this issue:

Also, check which Radio Firmware you have installed now. If you have 32.26.00.24U_4.04.00.03_2 installed, try downgrading to 32.24.00.22U_4.03.00.21_2.

Hmm... I've had a look at that thread, thanks for the pointer!
Too bad I'm in Europe . I changed to US, JAPAN, AUS and EURO, but it didn't help . I'll try the same with the .03 radio. I've flashed both the .03 and .04 radio's before, but not together with the instructions at the end of the mentioned thread.

3G not working, but HSDPA is.

Hi All,
For 2 weeks or so now I've been having an issue with my Hero's internet connection. Didn't notice specifically when it started as it only affects the 3G connection and I mostly get HSDPA in my area. I use WiFi at home anyway.
When the notification bar shows 3G, the upstream arrow flashes periodically but there is no traffic downstream. Market downloads fail, anything which requires an internet connection will timeout.
However as soon as it switches up to H connection, it starts downloading immediately. If I switch to 2G only GPRS and EDGE connections work fine too.
Around the time the issue started I was trying a few different 2.1 roms for the first time. Have flashed several different roms since and have the same issue. Currently using VillainRom5.5. I was already using Radio 63.18.55.06JU_6.35.09.26 but have reflashed this too. Have flashed the stock Orange RUU, RUU_Herrange_UK_2.73.61.5_release_signed_NoDriv er.exe, but the issue remains.
Didn't have a problem, especially at home, before trying the 2.1 roms. I have good signal regardless which connection I have, currently 3 bars.
Thought it might just be an issue around my house but have tested all over and it's the same. Became an issue this week as I was visiting Somerset and in area's without HSDPA. Had to switch to 2G only in order to get internet connection.
Have searched here and other forums but cannot find anything specifically like this, any help greatly appreciated!
Cheers,

hello,
I had a lot of problems with connections (3G/HSDPA/2G) with loose of signal.
I tried a lot of ROMS to solve this problem. But It wasn't the right way...
In fact, My SIMcard was defective. I had to change it, and now all is OK.
I'm not sure that it will be the right issue for you, but perhaps It could be...

Cheers for your reply.
Have contacted Orange today, the customer services guy tried some stuff and asked me to test and call back. Hasn't helped so will call them back in a mo and report back.

Hi,
I am having a very similar issue and I am also on Orange. My issue started after around the time I flashed Villian 5.3 but I doubt this is the issue as I have flashed other ROMS since and have the problem. Have you also done the 2.1 battery stuff by *#*#4636#*#*? I did this around the same time the issue started and I thought it was because I had set it to GSM (auto) but I put it back to WCDMA but that made no difference.
My phone keeps showing 3G then swapping to HSDPA. This is both an my house and in the city. I always got H no matter where I was but now keeps swapping after a couple of mins or when I use internet. I've reflashed ROM, radios and tried a friends Orange SIM and I get the same.

I also have the exact same problem on the 3 network in the uk, definately not a sim problem as before I rooted and flashed it all worked perfectly. Hasnt been too much of an issue as most of my city has hspda coverage but if I go out of town its a pain.
Problem started as soon as I flashed a villain ROM and is present in all 2.1 ROMs I have tried although I have noticed that the legend ports seem more stable and connect a little better, so am currently running the villain 4 ROM. Updating the radio made no difference and I am starting to wonder if it is some thing to do with using a CDMA port?

Yeah I did try that stuff, I too have set it back to WCDMA Preferred. Now you mention it I guess my issue did start around this time too so its likely to be linked.

It does seem too coincidental that we have done the same things and are having the same issues on Orange. I'm going to wait to see if ROM from the official 2.1 build sorts it out and if not swap the phone out. I've had Villian and now BeHero + and still have the issue. I've flashed different Radio's as well and that has not fixed it.

Ive had this problem for well over a month now, way before the gsm auto trick came on the forums and I started using it, I dont think thats the cause, dont think its a radio issue either as had it on two diff radio versions.
My issue started as soon as I flashed a eris port which as far as I know is cdma based and isnt that a different kind of network than we use over here??
Any devs want to chip in here and help some noobs plz?

I've always had this issue with Orange as well, regardless of ROM, prior or after to flashing. I thought it was just the Orange network capacity as when I use the phone out of peak hours (2-7am) its fine.

I have the stock Hero with 1.5, no roots or custom os & it happens to me on Orange UK.
No idea why, but don't think its to do with custom roms!

Yaeh i have the exact same issue, tried many different roms, including official orange roms. This issue started before i started playing with customer roms.
Anyone have any suggestions?

Just adding to the list. Same issue for me, Orange UK - not specific to any ROM (Stock or Custom)

I'm going to join the party and say I have this problem too.
Although I didn't notice until I read this and checked, I just assumed Oranges 3G network was unstable in peak times

I too am on orange uk and tried this and experienced the same issue.
The solution is just reflash rom and radio (no wipe etc so data remains). That fixed it for me.
Also don't mess with *#*#...... settings

I'm still having this issue, maybe it is just the Orange network thats to blame? Seems to be to a number of us cropping up.
Gonna get back onto Customer Services this weekend, see what they say this time.

Same problem here. I'm on Orange UK too. Seems like an Orange network problem rather than a ROM problem

Saw this on my G2 Touch Hero on t-mobile when using villainrom 5.2. Not seen it recently and don't think its related to flashing 6.0.

Thought I'd update this.
Been living with the issue since posting, tried a few roms, all with the same issue.
Tried the latest radio, that didn't help.
Flashed EzHero rom few days ago and 3G has been working fine since! Don't know whats in this rom which might do that, it doesn't display the 'H' icon anymore which is the only visual difference. Might just be coincidence but either way glad its working consistently again.

I've had the same issue here on the other side of the pond in Canada on the Telus Hero. I think it has something to do with the phone trying to default to the fastest connection. I'm assuming the providers don't want us connected to the faster networks constantly, so they have a disconnect on idle response; which in turn is being counter-acted by our hero's need for speed. That is one theory, but I have to include that when I first got my TELUS Hero, before rooting and installing MaDaCo 1.5 I would have stable 3G connections. Any ROM installed following the root of my phone has caused this same dilemma.

This is a big issue on orange one which I have never got to the bottom of.
Now my phone seems to work 99% of the time but it always switches to H before downloading.
It might be something to do with Orange switching to new "next generation" towers. Apparently last time I phoned orange my phone was connected to two towers (only supposed to be one) so it was impossible to triangulate my exact position.
This might have something to do with it.

[Q] Android Phone Signal Fluctuates

I'm with T-Mobile and the signal for my hd2 is solid on winmo, but when I boot android my phone signal fluctuates. It goes from 5 bars to 2 bars to none then back to 5 bars again and the cycle continues. I've tried several roms and radio changes as well as android built but that does not seem to fix the problem.
Does anyone know a way to fix this?
As of right now, I'm using Chucky with 2.12 radio and my favorite build Froyostone V2.

Mine does the same with froyostone v2 as well. Im running 2.08.50 radio. Frustrating!

Yep, have the same issue on Bangsters 1.3 build :\

same issue with o2 and Radio 2.10 tested with HyperDroid and Bangsters

I'm T-Mobile and my signal is different depending on where I am at! But if I find the sweet spot it stays dead on.

Same issue. with radio ver. 2.12.50.02_2.
Signal seems solid on WinMo but on Android Bangsters 1.3a it jumps sometimes to Edge insted of Hsdpa. it depends on where I am. Conn-type-RMNET - PPP does not work for me.
The bottom line the signal is beter on WinMo. Hope this will be solved on next build.

I concur... I just recently started using Android on my T-Mobile HD2 and can relate that the signal quality as well as data connection is sketchy at best. One second I'll have a full signal and the next I have none. Then once the signal comes back, any and all data services also don't work.
Using Darkstone V2 and Radio 2.12.50.2

Exactly the same for me which is a shame because its the only problem left I'm having. The signal is there and its strong then it disappears and just keeps running that cycle all the time.

Same here
Shubcraft 1.5 radio 2.11. sometimes it shows no signal, how ever i dont know if it is just the software or actually the phone does not have signal.

Same on froyostone + 2.12 radio.
changed to mdeejay Froyo Sense + 2.11 radio
no more "no signal every 2 min, gonna smash my phone on the floor" for me.

Let me test mdeejay's build, let's see if its better.

I have had the same problem, so i downloaded the "mdeejay_froyo_sense_v1.5_NOAXI " build, copied "rootfs.img" to my Andrid folder, restarted, and now it seems to not loose the signal at all. Full / almost full signal all the time.
I also tried to use "zImage" from the mdeejay-build. It also worked, but WiFi would not start at all. Just said "Fail", so i switched back
Not sure if this works for everyone, but it sure is worth a try...

in settings under phone/cell standby what percent do you have without a signal? Mine is usually really high 50-80%. I've been able to pull 32 hrs out of a single charge when its on the lower end.

Whenever you switch your zImage you have to also change your bcm4329 module, if not Wifi will not work.

I think we really need an exploration in radios in general. Pick a random set of builds and everyone switch out radios to see how connection goes. I live in a city that has the HSPA+ from T-Mobile and there are times I can't get voice to work on Miri 6.5/Bangers 1.3/2.12 (the latest) radio.

I am using chuckydriod with radio 2.12 and android build hyperdriod 1.2 using latest michyprima R11 kernal with axi scaling.
I have excellent radio performance in the following modes.
GSM only
Wcdma only
Dual mode rarely switches to GSM even when wcdma is dropping data connections in high GSM signal areas wich is a bug in my opinion.

Pure gold
Downloaded the Desire HD beta2 Android and i use the "rootfs" from that build...
Have not had any "zero-drops" at all, and i have signal in some bad areas where i had nothing before...

facing this problem too
using hyperdroid 1.5 and 2.12.50.02

I upgrade my radio to the newest one 2.14 on meedj's evo sense warm 1.0 thinking that it would help my phone signal, but it didn't help. Then i started messing around with my "network settings" and to my surprised it seemed to help. My cell signal still fluctuate but it never reaches "no bar".
Here's what I did:
Go to seetings, then wireless & network, mobile networks, network operators, then wait until you get 4 or 5 signal bars and click on "select automactically". I don't know what it does but it helps me and I hope it helps you too.
Note: you can also select "search network" and manually add your network in, it doesn't hurt trying. [/COLOR]
Let me know if this works for you.

Mytouch 4g HSPA+ Not working anymore?

let's start with what makes you think you "lost your 4g connection"?

I feel like i am having the same problem, when i first flashed CM7 i would get the occasional H signal but for the past week or so i have only seen the 3g signal. There was a brief moment where i noticed the H for a few minutes. Does this mean anything?

I'm running the royalthunder rom and I've noticed the same thing. I don't really see the h that much anymore. I live in phoenix.

Slower internet, and a lot more time using EDGE and 3G

Check your preferred network settings.
Dial *#*#4636#*#*
Select phone info
Scroll down to prefer network
I have better luck with GSM auto (PRL)
[via XDA app]

I have noticed the same thing. I made a backup of my original rom and settings, then flashed to cm7 just to check it out. I wasnt satisfied with it, so I switched back to my backup rom. I have noticed that my data latency and speed has been far worse than when I was unrooted and on the stock rom. Will changing the preffered network help this? Any idea what I inadvertantly modified while switching between roms? I thought the nandroid backup backed EVERYTHING up???

Although I'm still on 3g this has improved my speed noticeably. Now it feels like its more just a visual thing and not actually a network problem.

[Q] Unlocked HD2 Need Rom that connects with AT&T

Hello all I have a PROBLEM!
I have an unlocked HD2 using AT&T, my signal is extremely weak so my thoughts were to add an Android Rom in hopes to increase the signal but I have tried several NAND Roms:
RAFDROID
HYPERDROID CM7
NEXUSHD2 GINGERBREAD
HYPERDROID GBX
ARKAT DOUBLESENSE
REDUX V1.2
I am using the MAGLDR 113, installing using CWM 3.2. I am not sure which radio i have... perhaps that's the problem?
It would recognize the AT&T network and would say registering to AT&T but after 30 seconds or so it would say unable to connect at this time.
PLEASE help I am currently phoneless.
Thanks
PS it doesn't have to be android anything with a signal will work

Try this radio 2.15 its the newest one procedure is the same as installing magldr
1.make sure the phone is off
2 hold the volume button down and turn the phone on
3 connect your phone to your pc thru usb
4 flash the radio from your pc.
hope it helps
in the future post questions in Q and A section or you'll get flamed

Thanks for the link to the radio I appreciate it did not see to help the signal issue. In regards to improper posting that was an oversight on my part is there a way to delete it from here and post in the proper category?

it might just be your location...see if you get better signal elsewhere

Tapatalked u see

rom has nothing to do with the connection you're getting, if you have the latest radio(2.15.50.14) and the proper apn settings for att, then is definitely the service in your area. I have TMO and I get crap signal in my home with any and all roms, but once I'm outside I get good service, plus in data speed you'll only will get Edge/2G speed , but I'm sure you already knew that happens when using a TMO phone in ATT and vice versa .

I'm using my HD2 on AT&T and mine is working great. I'm running Rafdroid Desire HD Froyo. No signal problems at all.

Lets check whether your device is having a loose connection or not first. Put on your wifi, stand some feets away from the router and see if you can connect. If your having weak signal, stand near the router and check. If you still have a weak signal put on your bluetooth and see if you can discover any other bluetooth devices.
If you are having problem with these two connection as well, then my friend its time to open up your device and prepare for surgery.
Else, despite getting full wifi and bluetooth, if you are still having network problems, then place an aluminium foil on the back side of your device in full.
now see if you are having any improvement. These are just preliminary tests to check whether your device needs some serious disassembling.

I'm having the same problem, although I do get connections sometimes but then when i try to send a text or make a call it says network unavailable. I do have gprs data turned off on my phone's account with ATT. I messed with some settings in the phone options after dialing that *# thing and it worked but like i said after one text it just stoppped and when I go into network settings and click att it says registering and then after a few seconds it says unable to connect

After a few more hours of searching I found a way to get a much me stable connection. However, sometimes I lose signal but not like before, when I used to get a warning notification in the taskbar thing. What you have to do is go into the special phone settings by going to the dialer and typing *#*#4636#*#* where it says wcdma preferred you need to change it to GSM only and do a reboot and you should get much better signal.
